In an earlier chapter (pp. 31, 32) I have explained that in the adult the voluptuous sensation is closely associated with the psychosexual perceptions, associated, that is to say, with the mode of the contrectation impulse; I stated that as a rule the voluptuous sensation was experienced to the full in those cases only in which the sexual act was one adequate to the contrectation impulse of the person concerned. But when the association between the processes of detumescence and those of contrectation has not yet occurred, the voluptuous sensation is independent of the contrectation impulse. This explains the fact that in the child both the peripheral voluptuous sensation, and also the voluptuous acme and the sense of satisfaction, are more frequently independent of the processes of contrectation than is the case in the adult Gradually the two groups of processes become associated with one another; and, as we have learned, this association frequently occurs even in childhood. In the latter case, the voluptuous acme and the subjective sense of satisfaction ensue only when the sexual act or the sexual idea is adequate. But we must always remember that in the child more often than in the adult the voluptuous acme and the sense of satisfaction occur independently of the processes of contrectation. An ejaculation of fluid secretions does not invariably occur when masturbation is practised. Whereas in the adult masturbation ordinarily culminates in ejaculation, in the child this is not usually the case; at any rate, as regards many children the occurrence of ejaculation is not demonstrable. I refer in this connexion to what I have already stated on page 54 _et seq._ It is self-evident from what has been previously said that during the second period of childhood masturbation is more likely than during the first period to culminate in ejaculation.
